Project description:
"My current firmware runs on an STM32F0 and now needs both NB-IoT connectivity and GNSS positioning. The hardest piece for me is understanding and using the NB-IoT AT command set, so I want to focus there first, then work outward to full integration.

What I need from you
• A concise yet thorough walkthrough of the NB-IoT command syntax—each command’s purpose, required parameters, typical responses, and timing notes.
• A step-by-step power-up and network-attach sequence written for an STM32F0 UART interface (HAL-based), including code snippets I can drop straight into my project.
• Guidance on configuring the GNSS module, reading NMEA (or vendor-specific) sentences, and translating them into latitude/longitude in my application layer.
• Practical examples showing how to publish sensor data to a server or a Thingsboard cloud endpoint, plus how to receive downlink messages.

Acceptance points
1. I can issue the explained AT commands from my board and see the documented responses.
2. The modem registers on the network and successfully sends a test payload.
3. GNSS data streams into my firmware and decodes to valid coordinates.
4. A complete, compilable STM32CubeIDE project, or neatly separated C files, demonstrating the above.

Please keep explanations clear and modular so I can reuse the pieces across multiple products. I’m available to test code on hardware and provide logs as we iterate." (client-provided description)
